(1) By default, this clock signal is implemented as 'pad loopback' inside the device - the output signal is looped back through the input buffer
to serve as the internal reference signal. mmc1_clk and mmc2_clk have an optional software programmable setting to use an 'internal
loopback clock' instead of the default 'pad loopback clock'. If the 'pad loopback clock' is used, series termination is recommended (as
close to device pin as possible) to improve signal integrity of the clock input. Any nonmonotonicity in voltage that occurs at the pad
loopback clock pin between V_IH and V_IL must be less than V_HYS.
